INDIRECT RADIATSR- SPECIFICATION forming part of Letters Patent No.258,967, dated June 6, 1882.

' Application filed January 9, 1882. (No model.)

To all whom it may concern Be it known that I, ELISHA T. WEYM UTH, acitizen of the United States, and a resident of the city of Brooklyn,county of Kings, and State of New York, have invented a new and usefulImprovement in Indirect Radiators, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Myinvention relates to indirect radiators for heating buildings bysteam, where the radiators for heating'are placed inside of a draftboX;and the object of my invention is, first, to increase the heating orradiating surface and reduce the space occupied by the radiator; second,to prevent the air as it is being heated from passing in a straight linein a smooth current between the surfaces of the radiator. I attain theseobjects by theapparatus illustrated in the accompanying drawings, inwhich- Figure 1 is a view in perspective of a draftbox, wherein the airis heated in passing through it on its way to the registers, the dottedlines showing the radiator in position inside. Fig.2 is a cross-sectionof four sections of the radiator. Fig. 3 is a plan view of one side ofone section of the radiator, showing the partitions B B inside. Fig. 4is a section of the side of one section of the radiator, and a plan viewof one of the sections B B.

Similar letters refer to similar parts in the different figures.

A A are sections of a radiator, with corrugated surfaces on both sidesof each section, the corrugations on each side being of the same formand depth, the corrugations on one side being the reverse of those-onthe other side, having the same distance between each part, as shown inthe sectional view in Fig. 2. Each part or section A of the radiator iscomplete of itself, forming a corrugated square or rectangularbox,withaninlet-pipeforthesteam,

. as shown at E in Figs. 1 and 2, and an outlet-pipe for the steam, asshown at F in Figs. 1 and 2. Each part or section A of the radiatorbeing a duplicate or fae-simile of the others, when they are placedtogether a short distance apart, as shown in Figs. 1 and 2, a space isformed between the sections of a uniform width throughout. The two sidesa b of each section are held together by a narrow flat top, d, bottom 0,and ends 0 6.

Each section has, in addition to the top, bottom, ends, and corrugatedsides, two partitions, B B, extending from the top of the section nearlyto the bottom of the inside of the section, as shown in Figs. 3 and 4,which prevents the steam, when allowed to enter one of the sections AAof the radiator, from making a direct and unobstructed passage from theinlet steam-pipe E to the outlet steam-pipe F, thus breaking the currentor passage of the steam and causing it to heat all surfaces of theradiator equally. Having a corrugated surface on the sides of eachsection A, and a partition inside, holding the sides together, a verystrong radiator is made, being much more capable of withstandinga greatpressure of steam than where the sides are flat and without partitions.I

Having constructed the sections of the radiator as heretofore described,each section is joined to the inlet steam-pipe E by a right and leftthreaded nipple, N, as shown in Figs. 1, 2, and 3, and the other cornerof each section is joined to the outlet steam-pipe F by a right and leftthreaded nipple, N as shown in Figs. 1, 2, and 3. The number of sectionsin the radiator will depend on the size of the room to be heated, thesame being added to as the 00- E:

the bottom of the draft-box D and the bottom of 8 5 theradiator-sections A A, into which space the air to be heated enters, asshown atH in Fig; 1. This draft-box D has also a space between its topand the top of the radiator-sections A A, as shown in Fig. 1. The air tobe heated enters the box'at H in Fig. 1, passes upward and between theradiator-sect-ions, and passes into the flues at K, as shown in Fig. 1.The seetions A A- of the'radiator having the uneven surfaces on theirapproximating sides causes the current of air, in its passage upward, todeflect from the surface of one section to the surface of the othersection, and the reverse, continuously. By this motion all parts of thecurrent of air are caused to come in contact with the entire surfaces ofthe radiator-sections,- while the radiator-sections A A, being of oneuniform thickness, and the steam coming in contact with all parts ofsaid radiator-sections, a uniformity of heat and heating-surface ispresented to the air in its passage.

Having thus described my invention, what; I claim as my invention, anddesire to secure by Letters Patent, is-

1. In a steam-radiator of the character herein set forth, the similarsections A A, each having corrugated sides a b and partitions B B, theright and left threaded nipples N N, the inlet-pipe E and theoutlet-pipe I the several parts being arranged and combinedsubstantially in the manner and for the purposes set forth.

2. In a steam-radiator of the character herein set forth, the similarsections A A, each having corrugated sides a 'I) and partitions B B, theright and left threaded nipples N N, the inlet-pipe E and theoutlet-pipe F, and the box 20 or casing D, provided with the air-inlet Hat the bottom and the air-outlet K at the top, the several parts beingarranged and combined substantially in the manner and for the purposesand objects named. 2 5

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.
